Strange combinations

The Catholic patron saint St. Fiacre is in charge of (hold on!): gardeners, French cab drivers, and people suffering from haemorrhoids and veneral diseases.

What a combination. I can understand the connection between medicinal plants in gardens and diseases, but what are the French taxi drivers doing in there? Like Magnus, Brasse, and Eva said in the Swedish childhood TV program: - En ska bort! (one has to go). [this is kind of an internal joke for people that grew up in the 70s in Sweden]
